Configure HiveServer2 to use PAM Authentication

About this task

You can configure HiveServer2 to use Pluggable Access Modules (PAM). The configuration requirements for PAM differ based on the version of Hive that you have installed.

Hive Version		Default Configuration	Configuration Requirement
Hive 2.3	1904	MapR-SASL and PAM are enabled by default on a secure cluster.	No configuration is required.
	1901	MapR-SASL and PAM are enabled by default on a secure cluster.	No configuration is required.
	1808	MapR-SASL and PAM are enabled by default on a secure cluster.	No configuration is required.
Hive 2.1	1904	MapR-SASL and PAM are enabled by default on a secure cluster.	No configuration is required.
	1901	MapR-SASL and PAM are enabled by default on a secure cluster.	No configuration is required.
	1808	MapR-SASL and PAM are enabled by default on a secure cluster.	No configuration is required.
	1803	MapR-SASL and PAM are enabled by default on a secure cluster.	No configuration is required.

Configure HiveServer2 to explicitly use PAM Authentication

Procedure

In the hive-site.xml on each HiveServer2 node, set the hive.server2.authentication property to PAM:
```
<property>
  <name>hive.server2.authentication</name>
  <value>PAM</value>
</property>
```

Restart HiveServer2 to apply these changes:

maprcli node services -name hs2 -action restart -nodes <comma-separated list of nodes>
